ABSTRACT:
A modular jack electrical connector assembly 2 suitable for conditioning the signals in unshielded twisted pair wires for use with network components is disclosed. The modular jack 2 comprises a conventional insulative housing 4 and an insert subassembly 6 including insert molded front insert member 8 and rear insert member 10. Contact terminals 12 for mating with a modular plug extend from the front insert member 8 and into the rear insert member 10. The rear insert member 10 also includes signal conditioning components such as common mode choke coils 38, filter circuits 40 and transformers 54 suitable for conditioning the twisted pair signals for used in applications such as for input to and output from IEEE 10 Base-T network components. The insert molded body 30 of the rear insert member encapsulates the signal conditioning components to protect the components and to stabilize the component to achieve reliable repeatable performance. The insert molded body also stabilizes the position of the contact terminals 12 and leads 14 extending from the rear insert member 10 for attachment to external circuits, such as the external printed circuit board containing the interface processor for the specific application. The signal conditioning components can be soldered directly to the contact terminals 12 and leads 14 or they can be mounted on a signal conditioning printed circuit board 36 also encapsulated in the insert molded rear insert body 30.
